    .SYNOPSIS

        HTML snapshot of one baseline observation (offline). Not a findings report.

    .DESCRIPTION

        Tables per record type from baseline.json (or a FotonBaseline_* folder).

        Caps rows. Escapes every cell. Does not say the host is clean or compromised.

        The JSON file remains the source of truth for Compare-FotonBaseline.

    .PARAMETER Path

        baseline.json or a baseline package folder.

    .PARAMETER OutputPath

        HTML file. Defaults to Foton_Baseline.html beside the JSON.

    .PARAMETER MaxRows

        Max rows per table (default 200).

    .EXAMPLE

        New-FotonBaselineReport -Path D:\Baselines\FotonBaseline_PC1_20260822-120000Z

        Writes Foton_Baseline.html in that folder.

    .OUTPUTS

        Path to the HTML file.
